isoPropylpalmitate (Isopropyl Palmitate Ph. Eur. & USP/NF)
Odor: characteristic
Use: HallStar IPP-NF is an economical liquid ester made from the reaction of vegetal Palmitic Acid and petrochemical Isopropyl Alcohol. It conforms to the requirements of the National Formulary monograph for Isopropyl Palmitate. HallStar IPP-NF is a light non-occlusive emollient with a soft, dry, non-oily feel. It is used as pigment binder, diluent, and solubilizing agent for mineral oil, silicones, lanolin, and fragrances in many personal care product applications. HallStar IPP-NF is best stored in a cool dry place in the original sealed containers. Avoid prolonged storage above 32°C (90°F). Maintain above 15°C (59°F) to preclude freezing.
